Record Cullinan performance drives improvement in Petra’s full-year output
Diamond miner Petra Diamonds produced 3.2-million carats at its operations in the financial year ended June 30. The Cullinan mine’s performance, which contributed production of more than 1.9-million carats, was offset by lower production at Finsch and Koffiefontein, while the Williamson mine, in Tanzania, remained on care and maintenance.
